Tide water filtering tanks having high circulation

Abstract

A water filtering tank comprising a housing of the water filtering tank, water inlet pipe ( 3 ) installed on the housing receiving water into the tank, water distributing sheet ( 2 ) in which the said sheet is arranged inside the tank at the height lower than the inlet pipe ( 3 ) in which the said distributing sheet receives water flow through the inlet and comprises a plurality of pores positioned throughout the said sheet, rough filtering basket ( 1 ) in which the supporting lower surface comprises a plurality of pores and the said basket comprises rough filtering materials inside which arranged in the basket at the height less than the distributing sheet ( 2 ) and receives water flow through the said water distributing sheet, filtering material basket which is arranged inside the basket at the height less than that of the rough filtering basket ( 1 ) and comprises the filtering materials arranged into multiple layers and water outlet pipe ( 7 ) installed with the housing and releases water. Characterized in that the water filtering basket comprises a siphon tube supporting base ( 6 ) which is arranged at the lower part of the housing and further comprises a water outlet standing pipe ( 8 ) vertically installed on the said base and has the height less than the height of the inlet in which water is sucked out of the housing through the lower water outlet standing pipe ( 8 ) connected with the water outlet pipe ( 7 ) when water level filled inside the housing is at the same level as that of the water outlet standing pipe ( 8 ), siphon tube ( 10 ) covering the water outlet standing pipe ( 8 ) and further comprises snock tube ( 11 ) in which is in the U-shape having one end connected with the siphon tube at the predetermined height.

What is claimed is: 
     
       1. A water filtering tank comprising:
 a housing of the water filtering tank; 
 a water inlet pipe installed on the housing receiving water into the tank; 
 a water distributing sheet in which the said sheet is arranged inside the tank at a height lower than the inlet pipe in which the said distributing sheet receives water flow through the inlet and comprises a plurality of pores positioned throughout the said sheet; 
 a rough filtering basket in which the supporting lower surface comprises a plurality of pores and the said basket comprises rough filtering materials inside which arranged in the basket at a height less than the distributing sheet and receives water flow through the said water distributing sheet; 
 a filtering material basket which is arranged inside the basket at a height less than that of the rough filtering basket and comprises the filtering materials arranged into multiple layers; 
 a water outlet pipe installed with the housing and releases water; 
 wherein the water filtering basket comprises a siphon tube supporting base which is arranged at the lower part of the housing and further comprises a water outlet standing pipe vertically installed on the said base and has a height less than the height of the inlet in which water is sucked out of the housing through the lower water outlet standing pipe connected with the water outlet pipe when water level filled inside the housing is at the same level as that of the water outlet standing pipe, siphon tube covering the water outlet standing pipe and further comprises a snock tube in which is in the U-shape having one end connected with the siphon tube at the predetermined height. 
 
     
     
       2. The water filtering tank as cited in  claim 1  wherein the rough filtering basket comprises fins dispersedly arranged on the upper surface of the basket. 
     
     
       3. The water filtering tank as cited in  claim 2  wherein the rough filtering basket comprises a overflow water tube vertically installed on the surface of the said basket. 
     
     
       4. The water filtering tank as cited in  claim 1  wherein the area inside the filtering material basket is divided into multiple spaces for containing filtering materials. 
     
     
       5. The water filtering tank as cited in  claim 1  further comprising siphon tube connector arranged to connect siphon tube with the siphon tube supporting base. 
     
     
       6. The water filtering tank as cited in  claim 1  wherein the rough filtering basket comprises overflow water tube vertically installed on the surface of the said basket.
